Is there a way to remove the authorization prompt from command-line instances of Instruments (Xcode)?

I am currently using Instruments via a bash script to initiate the command-line interface to start up runs of the Automation plug-in.

With 4.2, this worked well enough, however with the upgrade to Xcode 4.3, I am now being prompted for an authorized user to 'analyze other processes'. No user is ever actually authenticated, even if the correct credentials are granted. I get the following error:

Failed to authorize rights (0x20) with status: -60007.
2012-02-27 19:30:37.232 instruments[54151:1c03] Failed to connect to local pid watcher     service: (os/kern) failure

Even with the authentication failure, the Automation plug-in executes, however this requires my script to have a physical babysitter enter credentials, which in many ways defeats the purpose of these command-line runs. Is it possible to add the user details as arguments? Or is there some other way to skip over this prompt without requiring a person at the keys?

This authorization dialog appears when you try to run UIAutomation tests from the GUI for the first time.

Once the authorization dialog has been answered in the GUI, the prompts stop appearing on the command-line. This kind of work-around doesn't seem valid as an 'answer' though.

Okay I think I got it working.

Here are some more details about how to remove xcode command line authorization prompt

What I did was the following:

  • Mark jenkins user as admin (unfortunately it seems that there is no other way atm)
  • Go to /etc/authorization
  • search for key system.privilige.taskport
  • change value of allow-root to true

    <key>system.privilege.taskport</key>
    <dict>
        <key>allow-root</key>
        <false/> // change to -> <true>
        <key>class</key>
        <string>user</string>
        <key>comment</key>
        <string>Used by task_for_pid(...).
        ...
    </dict>
    

Now I am being able to use jenkins to run my UIAutomation-Tests via Command Line Script
